Linux fuu

Some helpful things for Linux

Systemd Maximum Number of Openfiles

  • systemd does not rely on ulimit (as opposed to Fedora), so /etc/security/limits.conf is ignored
  • The solutions is to use LimitNOFILE=10000 (with an appropriate value) in the .service file
    • systemctl daemon-reload
    • systemctl restart <service>
    • systemctl show -p LimitNOFILE <service>
